Some great advice posted already.....
Been using a TRX1 for over a year now and it's great: maybe not the best for searching for new signals, but great at scanning known channels. Learn the Fn+0 keypress. But as gmanbelfast points out, there is a fantastic feature of being able to set a limit search pick DMR and/or NXDN only, and you can let it run and it will hunt out all digital signals in the band. It doesn't work that well for this on auto mode/analogue as it'll hit on a signal, and must be manually forwarded on each time (there is no auto timeout seen on other scanners, such as uniden). DMR simplex is as good as a transceiver (the Unidens are awful). NXDN is great too (the Unidens don't cover this - yet). Pity the TRX only searches one band at a time. Spectrum Sweeper is ok, but not as good as Uniden Close Call (DMR simplex being the exception).
SD cards: tried loads on my Unidens and TRX1: I think this is the best I've come across to date:
https://www.amazon.co.uk/SanDisk-SDSDQQ ... -032g-g46aProgramming with a spreadsheet: the trick is to learn how to setup a template, write all the scanner channels you want to the spreadsheet, CTRL+C the list including the header, then import into EZScan (Ezscan>Conventional Freqs>Import From Clipboard) This helped me a lot....I've added some examples for Short Term Hire freqs too:

Recording: I default all channels to record audio to the SD card. Under the audio tab in EZScan, this allows you to review, playback, sort all the recordings on your SD card. Hint learn to use the EZScan>Audio>Copy functionality. It'll copy all he recordings to your PC/laptop, but also sort them into folders as per the Alpha Tag on the channel. Great for offline analysis. You can also just copy the raw .au audio recordings off the SD card too.
There's also a great little tool called Auparse
